San Ysidro Mountain Trail is a 7 mile out and back trail located near Borrego Springs, CA and is only recommended for very experienced adventurers. The trail is primarily used for hiking and is accessible from November until April.
We came. We saw. We conquered. This is a really tough hike. Major boulder jumping/low level climbing required. Lots of cactus and agave plants. So be prepared to be sliced up all over. Truly rewarding if you make it all the way up to the summit.
